Usual causes are:
1. Something in the drain path blocked. Symptoms: You can hear the drain pump running at the appropriate bits of the cycle, but if you you open the door the instant the pump stops, there is still a pool of dirty water in the bottom. Solution: Follow the path from strainer through drain pump to drain hose, find and eliminate the blockage. Most likely points are the strainer and the inlet to the pump. Hint: You can identify the drain pump by following the drain hose and seeing what it's attached to.
2. Drain pump broken. Symptoms: Usually, you won't hear the pump running at all at the appropriate times; if it does run, it won't sound right. Solution: Take it off and open it up, see if something is blocking the impellor (in which case, fish it out). Spin the impellor with your fingertips; If it won't turn at all, you need to find out why it has siezed (may be fixable) can you feel it turning the motor (a very magnetic, "flippy" sensation). If you can't, the impellor has probably become unstuck from the shaft. You may be able to glue it on, but this fix is unlikely to last very long. Use a multimeter to measure the resistance of the motor windings. If madly different from a few hundred ohms, again a new motor might be necessary. Hint: The pump motor and impellor can usually be bought separately from the pump housing as a much cheaper unbranded part.
3. Back-siphoning from the waste plumbing. Symptoms: You can hear the drain pump running normally at the appropriate times, and if you open the door the instant the pump stops, the machine appears to be empty, but then quietly fills up with dirty water. Solution: There is meant to be an air break (or in some installations and anti-siphon valve)where the machine's drain hose enters the domestic drainage drainage system. Unblock/unjam this. Hint: After fixing this, run the machine empty on the hottest, longest cycle it has; some of that dirty water may not originally have come from the dishwasher.

Mkae sure you are running kitchen hot water faucet before starting dish washer. If not you are getting mostly a cold water wash thru out the cycle. Also make sure the jet dry dispenser is full. Always use the liquid jet dry as the small cubes you can get do not work nearly as well.

All the newer ons will leave a little water in them. They will not drain all the water. It will leave the center part in the bottom with water. the reason is that when the pump cuts off the water that is in the line will come back to the washer.That is just the way they are. There is nothing wrong with it.HOPE this helps.

Check to make sure regular dish soap did not end up getting inside the dishwasher. This will create a lot of suds that will overflow onto the kitchen floor. Standing water from not draining can mean the drain hose is clogged somewhere or the check valve has something caught in it. If you remove the front kick plate, you will be able to check those.http://tclaundryrepair.com/

the first thing that your dishwasher does when you turn it on is drain when you turn it on you hear a motor running then it stops then it fills start the washer when it stops to start filling open the door should be no water in the unit if there is you have a drain problem and in fact are washing your dishes in dirty water can be several things that can cause drain problems a piece of food blocking the line at the sink where the drain goes in if its run to a disposer there is a knockout plug that should be removed just stick your finger in there to see if it was removed get you installation instructions and read the part about not removing the drain loop but just about all the time installers will lol if you cant find the instructions go to www.frigidaire.com under customer support can down load them there let me know what you find
